When the recipient does not have keys and certificates

Here is how you communicate securely with end customers, patients, applicants, tenants …

Z1 SecureMail Messenger lets you encrypt emails with communication partners who aren’t equipped with a professional IT infrastructure—making it especially easy for your contacts because they don’t have to install any software. Z1 SecureMail Messenger messages can be decrypted anywhere in the world on any device, whether desktop, PC, or smartphone. Encrypted replies are also possible. This way, you can finally use email instead of snail mail for your exchanges with end customers, clients, patients, job applicants, tenants, and everyone else. And you fulfill all IT security, data protection, and data compliance requirements with verifiable proof at all times for your email communication.

… and business partners without a professional encryption solution

For exchanges with business partners who have not yet invested in encryption technology or those using technologies incompatible with recognized S/MIME and OpenPGP standards, Z1 SecureMail Messenger is an effective solution for spontaneous encryption. Z1 SecureMail Messenger is also a proven solution for international mail exchanges when governments do not support certificate-based encryption.

Practical as a fallback or standard solution

Z1 SecureMail Messenger is often used as a fallback to certificate-based encryption with S/MIME or OpenPGP via the Z1 SecureMail Gateway. Outgoing emails to be encrypted are checked by the Gateway to determine whether a certificate exists for recipient addresses. If not, the message is automatically encrypted and sent via the Z1 SecureMail Messenger.

You can also set Z1 SecureMail Messenger as the default for all or part of your email communications. Additionally, you can enable your employees to trigger encryption themselves: Via user commands, they can determine if and with which method a message is to be encrypted.

Your communication partners can securely reply to your emails via the Z1 SecureMail Portal

High User Acceptance

…through intuitive use, a self-service portal, and a customizable web interface 

For your employees, nothing changes in terms of email processing. They send and receive emails directly via their familiar email program. And Message tracking keeps them updated about the status of sent emails.

With Z1 SecureMail Messenger, the recipient receives a sophisticated and intuitively usable secure communication tool. The available delivery methods are managed centrally by your administrator. Parallel use of the three options can also be useful: the recipient can independently choose and switch between delivery methods. We will be happy to advise you on the right solution for your specific situation.

The users themselves assign the password to decrypt confidential emails during account setup. The “forgotten password” function, which the user also operates, is available, of course – a user helpdesk is generally not required.

The Z1 SecureMail portal matches your brand colors

You can completely customize the Z1 SecureMail Messenger web interface with your corporate colors. Z1 SecureMail Messenger is not only a secure and GDPR compliant communication tool with your customers. You also make a valuable marketing investment that strengthens trust in your brand.
